UNGAYISEBENZISA KANJANI I-ZINC OXIDE ARRESTER TESTER?

Ekusetshenzisweni kwesikhathi eside kwezithiyo zokubopha i-zinc oxide, ukuguga kokuvikela kuvame ukwenzeka. Kungase kubukeke kujwayelekile ngaphandle, kodwa ingaphakathi alifaneleki ukuqhubeka nokusebenza. Ngakho-ke, kuyadingeka ukuhlola ukusebenza kokuvikela kokuvikela izithiyo zokubopha i-zinc oxide ngesikhathi. Kusetshenziswa isihloli sokubopha i-zinc oxide, ngakho-ke ungasisebenzisa kanjani isihloli sokubopha i-zinc oxide?

Isihloli sensimu ye-zinc oxide arrester siyithuluzi elikhethekile lokuhlola izakhiwo zikagesi ze-zinc oxide arrester. Sifanele ukuthola ukwehluleka okuphilayo noma ukwehluleka kwamandla kwe-zinc oxide arrester yamazinga ahlukahlukene e-voltage, kanye nokubona ngesikhathi amaphutha ayingozi njengomswakama ekushiseni kwangaphakathi kwemishini kanye nokuguga kwama-valve plates.

Imishini ilula futhi kulula ukuyisebenzisa, futhi yonke inqubo yokulinganisa ilawulwa yi-IPC, i-total current elinganisiwe, i-resistive current kanye ne-harmonics yayo i-MOA, i-frequency reference voltage kanye ne-harmonics yayo, amandla asebenzayo kanye nesigaba, i-voltage yangempela kanye ne-current waveform. Ithuluzi lisebenzisa ukuhlaziywa kwe-digital waveform, ukuhlaziywa kwe-harmonic kanye nemiphumela enembile, indlela yokuhlunga yedijithali ezinzile yokuphazamiseka kwesofthiwe, kanye nokuhlaziywa okunembile kokuqukethwe okuyisisekelo kwe-harmonic okuphindwe kathathu kuya ku-7, futhi linqoba isigaba sokuphazamiseka, isigaba esifanele se-resistance current Measure eduze kwe-arrester.

Uma kwenzeka ugesi we-transformer ungasebenzi, sicela uxhume ucingo oluqinile lwensimbi kanye ne-test transformer kuqala, bese uxhuma ucingo lokuhlola lwamanje (izintambo eziphuzi, eziluhlaza neziphuzi zezintambo ezintathu eziyinhloko zixhunywe ngokulandelana emaphethelweni aphansi ezibambezeli ezintathu ze-zinc oxide), bese ekugcineni uxhuma ucingo lokuhlola i-voltage lokumelana (izintambo eziphuzi, eziluhlaza nezibomvu zezintambo ezine eziyinhloko zixhunywe ngokulandelana kolunye uhlangothi lwe-transformer measuring winding, kanti ucingo olumnyama luxhunywe kolunye uhlangothi lwe-transformer measuring winding, naka isiqondiso, uma izinkomba zingenakuqondiswa).

Uma ihlanganiswe nomugqa wokuhlola wamanje, okokuqala, ngokuya ngobukhulu bamanje, umugqa wokuhlola wamanje ufinyelela ebangeni eliphezulu lomsingathi “0-2mA” noma “>2mA” (ijika elijwayelekile le-2-10mA >2mA), bese kuba yilokho okushiwoyo Ngakolunye uhlangothi lwendlela, i-oxide MOA iyancishiswa. Indlela yokuxhuma umugqa wokuhlola we-voltage ukuxhuma imitha kuqala, bese uxhuma i-transformer test winding. Ngemva kokuhlola izintambo ezifanele, khulisa kancane i-voltage ku-voltage yokusebenza ye-zinc oxide arrester, bese usebenzisa ithuluzi ukuqala ukuhlolwa.
